Lol "when the queen dies", people see someone fall down in a trailer and all of a sudden that character is definitely dying in the expansion. Also the storyline is hive focused because they're the most intimately involved with the darkness. The fallen are just jelly we took their girlfriend - I mean Dyson sphere - and cabal are derpin around just trying to take over stuff because they need more room for their empire or something. The vex are also around but they're not really involved with the darkness, they're just trying to become gravity's brother.
